It would be negative. Negative x negative = positive. Positive x Negative =negative. Negative x positive = negative.

The product would be negative. Since there are three negative integers, the product would be negative. Two negatives make a positive, but another negative makes the end result negative.

Paul [167]

The total cost in 5 hours is $225

Given that the charges of a supply fee of an artist is $50

The charges per hour classes is $35

The total cost is expressed by c

The number of hours expressed by h

We need to calculate the total cost in 5 hour lesson

As per the given statement ,

C= 50 +35h

Where h is the number of hours

h = 5 hours

C = 50 + 35h

C = 50 + 35(5)

C = 50 +175

C = $225

The total cost in 5 hours is $225

What is the distance between (4,8), 6=y+ 2x

docker41 [41]

Answer:

2√5

Step-by-step explanation:

The formula for the distance between a point (x, y) and a line in general form, ax +by +c = 0 is ...

$\text{distance}\,=\dfrac{|ax+by+c|}{\sqrt{a^2+b^2}}$

The general form of your equation for the line is ...

2x +y -6 = 0

so the distance to point (x, y) = (4, 8) is ...

$\text{distance}\,=\dfrac{|2\cdot 4+8-6|}{\sqrt{2^2+2^2}}=\dfrac{10}{\sqrt{5}}=2\sqrt{5}$

The distance between the point and line is 2√5.
